A Class Mercedes-Benz ECU fixed A Class Mercedes-Benz ECU fixed 5/5

Very good communication by text and emails at every stage of the process. ECU fixed and returned prompyly. My ECU and engine now works perfectly and it has saved me scrapping the car, as a new ECU from Mercedes would have cost 3x the cars value. Great service, highly recommended. Thanks.

Rebuild of ECU/MAFS Rebuild of ECU/MAFS 5/5

I had problems with my wife 1999 MB a160 and after some research I found on a dedicated MB trouble shooting site a reference to ecutesting. The experience was very professional, so far after 200km since I received the refurbished ECU/MAFS the car is running much better and the fuel economy is a lot closer to the manufacturer specifications. I choose because of their lifetime warranty. So far so good.
